Summary: Enables Atg12 activating enzyme activity and Atg8 activating enzyme activity. Involved in several processes, including cytoplasm to vacuole targeting by the Cvt pathway; piecemeal microautophagy of the nucleus; and post-translational protein modification. Located in cytosol; membrane; and phagophore assembly site. Used to study nervous system disease. Human ortholog(s) of this gene implicated in autosomal recessive spinocerebellar ataxia 31. Orthologous to human ATG7 (autophagy related 7). [provided by Alliance of Genome Resources, Jul 2025]

What's a GeneRIF?

Atg7 recognizes Atg8 through multiple steps, which would be necessary to induce a conformational change in Atg7 that is optimal for the activation reaction.
Title: Atg7 Activates an Autophagy-Essential Ubiquitin-like Protein Atg8 through Multi-Step Recognition.
This study used electron microscopy to measure the size and number of autophagosomes formed with limiting amounts of Atg7 and found them to be both smaller and fewer than normal. This suggests that Atg7 may have an Atg8-independent role in autophagosome initiation in addition to its Atg8-dependent role in autophagosome expansion.
Title: Control of autophagosome size and number by Atg7.
The autophagic E2 enzymes Atg3 and Atg10 share the same binding pocket of E1 enzyme Atg7 and provide a framework for understanding the E2 conjugation reaction in autophagy.
Title: Structure of the autophagic E2 enzyme Atg10.
The structure of the C-terminal domain of Atg7 in complex with Atg8 shows the mode of dimerization and mechanism of recognition of Atg8.
Title: Insights into noncanonical E1 enzyme activation from the structure of autophagic E1 Atg7 with Atg8.

NP_012041.1

Autophagy-related protein and dual specificity member of the E1 family; mediates the attachment of Atg12p to Atg5p and Atg8p to phosphatidylethanolamine which are required steps in autophagosome formation; E1 enzymes are also known as ubiquitin-activating enzymes; involved in methionine restriction extension of chronological lifespan in an autophagy-dependent manner
